Managing RabbitMQ with RabbitMQTools

RabbitMQTools is a separate module for managing RabbitMQ over the REST API. It was originally written by @mariuszwojcik, with slight modifications from @ramblingcookiemonster.

Skip this section if you're just interested in using PSRabbitMQ to send and receive messages.

# Install the module
    Install-Module RabbitMQTools

# No PowerShellGet module?
    # Download RabbitMQTools
    # Unblock the archive
    # Copy the RabbitMQTools module to one of your module paths ($env:PSModulePath -split ";")

#Import the module
    Import-Module RabbitMQTools -force

#Get commands from the module
    Get-Command -module RabbitMQTools

#Get help for a command
    Get-Help Get-RabbitMQOverview

#Define some credentials.  You need an account on RabbitMQ server before we can do this
    $credRabbit = Get-Credential

#Convenience - tab completion support for BaseUri
    Register-RabbitMQServer -BaseUri ""

#I don't want to keep typing those common parameters... we'll splat them
    $Params = @{
        BaseUri = ""
        Credential = $credRabbit

#Can you hit the server?
    Get-RabbitMQOverview @params

#This shows how to create an Exchange and a Queue
#Think of the Exchange as the Blue USPS boxes, and a queue as the individual mailboxes the Exchanges route messages to
    $ExchangeName = "TestFanExc"
    $QueueName = 'TestQueue'

#Create an exchange
    Add-RabbitMQExchange @params -name $ExchangeName -Type fanout -Durable -VirtualHost /

#Create a queue for the exchange - / is a vhost initialized with install
    Add-RabbitMQQueue @params -Name $QueueName -Durable -VirtualHost /

#Bind them
    Add-RabbitMQQueueBinding @params -ExchangeName $ExchangeName -Name $QueueName -VirtualHost / -RoutingKey TestQueue

#Add a message to the exchange
    $message = [pscustomobject]@{samaccountname='cmonster';home='\\server\cmonster$'} | ConvertTo-Json
    Add-RabbitMQMessage @params -VirtualHost / -ExchangeName $ExchangeName -RoutingKey TestQueue -Payload $Message

#View your changes:
    Get-RabbitMQExchange @params
    Get-RabbitMQQueue @params
    Get-RabbitMQQueueBinding @params -Name $QueueName

#View the message we added:
    Get-RabbitMQMessage @params -VirtualHost / -Name $QueueName

        # = the number in the queue
        Queue = name of the queue
        R = whether we've read it (blank when you first read it, * if something has read it)
        Payload = your content.  JSON is helpful here.

              # Queue                R Payload
            --- -----                - -------
              1 TestQueue            * {...

#View the payload for the message we added:
    Get-RabbitMQMessage @params -VirtualHost / -Name $QueueName | Select -ExpandProperty Payload

        JSON output:

            "samaccountname":  "cmonster",
            "home":  "\\\\server\\cmonster$"

#Example processing the message
    $Incoming = Get-RabbitMQMessage @params -VirtualHost / -Name $QueueName -count 1 -Remove
    $IncomingData = $Incoming.payload | ConvertFrom-Json
    #If something fails, add the message back, or handle with other logic...

    #It's gone
    Get-RabbitMQMessage @params -VirtualHost / -Name $QueueName -count 1

    #We have our original data back...

    #There are better ways to handle this, illustrative purposes only : )

#Remove the Queue
    Remove-RabbitMQQueue @params -Name $QueueName -VirtualHost /

#Remove the Exchange
    Remove-RabbitMQExchange @params -ExchangeName $ExchangeName -VirtualHost /

#Verify that the queueu and Exchange are gone:
    Get-RabbitMQExchange @params
    Get-RabbitMQQueue @params


This is a module for sending and receiving messages using a RabbitMQ server and the .NET client library. Originally written by CD, slight modification by @ramblingcookiemonster.

# Install the module
    Install-Module PSRabbitMQ

# No PowerShellGet module?
    # Download PSRabbitMQ
    # Unblock the archiveiles
    # Copy the PSRabbitMQ module folder to one of your module paths ($env:PSModulePath -split ";")

#Import the module
    Import-Module PSRabbitMQ

#List commands in PSRabbitMQ
    Get-Command -Module PSRabbitMQ

#Get help for a function in PSRabbitMQ
    Get-Help Send-RabbitMQMessage -Full

#Define a default RabbitMQ server and get a credential to use
    Set-RabbitMQConfig -ComputerName
    $CredRabbit = Get-Credential

#Set some common parameters we will always use:
    $Params = @{
        Credential = $CredRabbit
        Ssl = 'Tls12' #I'm using SSL... omit this if you aren't

#Assumes an exchange and bound queue set up per RabbitMQTools example:
    #$ExchangeName = "TestFanExc"
    #$QueueName = 'TestQueue'

#Start waiting for a RabbitMQ message for 120 seconds
    $Incoming = Wait-RabbitMQMessage -Exchange TestFanExc -Key 'TestQueue' -QueueName TestQueue -Timeout 120 @Params

#Open a new PowerShell Window import PSRabbitMQ, and send a persistent message
    Send-RabbitMQMessage -Exchange TestFanExc -Key 'TestQueue' -InputObject "Hello!" -Persistent @Params

#Send an arbitrary object
    $SomeObject = [pscustomobject]@{
        Data = $(Get-Date)

    Send-RabbitMQMessage -Exchange TestFanExc -Key 'TestQueue' -InputObject $SomeObject -Persistent -Depth 2 @Params

            # InputObject is serialized when sent,
            # deserialized on the receiving end.
            # No need for messing with JSON

Initial changes

Temporary section to document changes since reciept of code. Will retire this eventually and rely on git commits.

  • 2015/6/23

    • Added option for SSL connections
    • Added option for authentication
    • Created public New-RabbitMQConnectionFactory function to simplify handling the new options
    • Created Add-RabbitMQConnCred private function to extract username/password from cred and add to factory
    • Created New-RabbitMQSslOption private function to simplify setting SSL options.
      • Note: the CertPath/CertPhrase/AcceptablePolicyErrors aren't specified by any calls to the function. Have not tested these.
    • Renamed private parse function to ConvertFrom-RabbitMQDelivery, made it public. Allows parsing from Register-RabbitMQEvent.
    • Wasn't sure how these were being used. Added handling for specifying an existing queue name and associated details (e.g. durable)
    • Converted timeouts to seconds
    • Added a LoopInterval (seconds) parameter for dequeue timeout
    • Added comment based help
    • Made asinine changes to formatting and organization. Sorry!
    • Wrote no new tests. Sorry!
  • 2015/6/24

    • Replaced client dll with latest bits
    • Resolved issue with credential handling due to dll changes
    • Added config handling for computername (get/set rabbitmqconfig) on appropriate functions
    • Added persistent option for sending messages


I don't know what messaging is and I'm terrible with code. Apologies for ugly, inefficient, or broken stuff : )


  • Break down functions a bit more. For example, offer functions to handle acknowledgements. I might retrieve a message requireing acknowledgement, and only send the ack down the line if my code meets certain criteria.
